The woman charged with killing her uncle over the weekend was ordered to undergo a mental health evaluation on Monday.

Yvonne Lewis, 36, is charged with fatally shooting Clive Francis in a Hyde Park home on Saturday afternoon.

Assistant District Attorney Ian Polumbaum told the court that Lewis had been staying at the Wood Avenue residence since moving back from Georgia earlier this year. She had been reclusive and acting erratically, Polumbaum said, so relatives called Francis, because of their relationship, believing that he would calm her down.
